标称电感量 | 感量偏差 | |||
Nominal inductance(μH) | Tolerance | |||
第一色环 | 第二色环 | 第三色环 | 第四色环 | |
1st color zone | 2nd color zone | 3rd color zone | 4th color zone | |
第一数字 | 第二数字 | 第三数字 | ||
1st digit | 2nd digit | 3rd digit | ||
黑Black | 0 | 0 | × 100(1) | M:±20% |
棕Brown | 1 | 1 | × 101(10) | |
红Red | 2 | 2 | × 102(100) | |
橙Orange | 3 | 3 | × 103(1000) | |
黄Yellow | 4 | 4 | × 104(10000) | |
绿Green | 5 | 5 | × 105(100000) | |
蓝Blue | 6 | 6 | ||
紫Purple | 7 | 7 | ||
灰Gray | 8 | 8 | ||
白White | 9 | 9 | ||
金Gold | / | / | × 10-1(0.1) | J:±5% |
银Silver | / | / | × 10-2(0.01) | K:±10% |
*例如e.g. :
标称电感量及偏差为22uH,±5%的电感器其色码为:红+红+黑+金;
If nominal inductance & tolerance is22uH,±5%, respectively red+red+black+gold should be marked;
标称电感量及偏差为1.0uH,±10%的电感器其色码为:棕+黑+金+银;
If nominal inductance & tolerance is 1.0uH,±10%, respectively brown+black+gold+silver should be marked;
标称电感量及偏差为0.22uH,±20%的电感器其色码为:红+红+银+黑。
If nominal inductance & tolerance is 0.22uH,±20%, respectively red+red+silver+black should be marked.
备注:LGA0204 由于体长较小,只标注前三条代表标称电感量的色码。
NOTE: Only the first three color zones are marked on the body of LGA0204,due to the small body size.
